Latex reader fails parsing \author{} if it contains empty lines

[aronfiechter]

pandoc 2.9.2.1

When converting this document with the command pandoc -s -f latex -t native main.tex:

\documentclass{article}

\begin{document}
    \title{Document title}
    \author{
        Me

    }
    \maketitle
\end{document}

the parser fails with this error:

Error at "source" (line 8, column 1):
unexpected ()
    }
^

It also fails if the empty line comes before "Me".
If the \author command is moved before \begin{document}, then the parser fails silently (i.e., no "author" is included in the parsed Meta).

When removing the empty line inside the author block, instead, the command successfully completes and Meta containns the author list.

Using pdflatex, everything rennders perfectly in all cases.
My use case is converting the raw tex code into markdown, for purposes of text extraction.
